>> Autopackage looks really great, and I'm very impressed with it, but it's gonna be a challenge to get people to use and accept it.

No no no, it's going to be a 'challenge' to get _developers_ to use and accept it, not users.. (remember, autopackage downloads/installs itself when not installed on the system)

Why should they (the users) not choose to d/l an autopackage instead of RPM/tarball/whatever if the former is much easier to use and does much more work related to system integration of the packaged program?.

There's almost no cons with this system so I really don't see any challenge..

/me, being a developer for an unreleased OSS project, is definitely going to use it, so that's 1 developer less to be convinced
